Brendan Horan remains tight-lipped

Brendan Horan is remaining tight-lipped about progress of an investigation into allegations he took large sums of money from his late mother's account.

Last week the MP he was stood down by New Zealand First leader Winston Peters who told him to return to Tauranga to provide evidence to clear his name.

Horan today, said lawyers were involved but refused to to give further details about the process or when it might be completed.

"I've got no comment to make. I've got it all in the hands of the lawyers, so I can't comment," he said.

He hoped to have the issue sorted "as soon as possible".

Horan said he was simply getting on with the job.

"I'm doing exactly what the leader of my party asked me to do and I'm still doing constituency work and doing exactly what Winston said in clearing up this pathetic mess."

The allegations came from Horan's brother Mana Ormsby, who said the bank statements showed a large number of withdrawals from TABs and ATM machines near Mr Horan's office in Mount Maunganui, Auckland and Hamilton.

An initial investigation suggested about $85,000 was missing from his mother's account, he said.
